All my online life I've read of people doing this and sometimes they're happy with the results and sometimes they're not.
I think chemistry is a lot more involved than most people think, kind of like making a cake. One person makes a cake by throwing all the ingredients in at one time, mixing it up and baking and the cake comes out flat and hard. Another person follows the directions and mixes specific ingredients in specific ways and then bakes the cake and it comes out tall and fluffy.
Mixing a batch of wax, sealant or a coating is likely a LOT more complicated than making a cake and I don't think you can simply mix one product with another and actually have the end results be something that will work as well as a product made by a real chemist.
I don't have any problems with someone trying, heck it's your wax do as you will but I would suggest instead of trying to mix products to make a new distinct product, do some research and you'll probably find whatever it is you're trying to make is already available in a ready-to-use form.
The only exception to the above is if you have a company that makes products that are formulated, designed and intended to be mixed, like Duragloss and Ultima for example...
Dodo Juice also offers people a way to make their own wax... Mike Phillips & pj Aass Show YOU How to Make Your Own Wax! How to Machine Wax and Seal the Paint
After the polishing step it's time to seal the paint with a coat of wax. For this we're going to use the Cucumber Explosion my son and I made over the Thanksgiving weekend. Cucumber Explosion!
